Abstract
Background: Temporomandibular disorders (TMD) are characterized by the presence of temporomandibular joint (TMJ) and/or masticatory muscle pain and dysfunction. Ultrasound therapy and low-level laser therapy (LLLT) have been recognized as therapeutic modalities for the treatment of TMD, especially when the presence of inflammatory pain is suspected. This study aims to compare the efficacy of the two treatment modalities in various TMJ disorders. Objective: The aim of this study was to evaluate the efficacy of low intensity or LLLT and Ultrasound therapy in the treatment of patients with TMD. Materials and Methods: A sample of 30 individuals, divided into two groups presenting signs and symptoms of TMD (I - LLLT and II - Ultrasound therapy) was taken. Both therapies were done in a total of 14 sessions. Therapy was performed for 5 days within the 1st week and then on the 30th day and the 60th day. The visual analogue scale was used to evaluate pain, digital vernier calliper used to evaluate mouth opening. Deviation from normal motion and clicking were also noted on opening and closing. The analysis of variance for repeated measurements and Tukey’s tests were used for the statistical analysis. Results: The results showed an increase in maximum mouth opening and a decrease in tenderness to palpation for both groups. Results also showed a decrease in clicking sound and deviation in both groups, although more evident for the low-level laser group. Conclusion: Authors concluded that both therapies were effective as part of the TMD treatment though lasers proved better. However, caution is recommended when judging the results due to the self-limiting aspect of musculoskeletal conditions such as TMD.
